Abstract

This document defines a set of cipher suites to add client credential
protection to the Transport Layer Security (TLS) protocol. By
negotiating one of those ciphersuites, the TLS clients will be able
to determine for themselves when, how, to what extent and for what
purpose information about them is communicated to others. The
ciphersuites defined in this document can be used only when public
key certificates are used in the client authentication process.
